NOTES:

1.Factory wiring is in accordance with UL 1995 standards. Field modifications or additions must be in compliance with all appli- cable codes.

2.All units or modules have single point primary power connec- tion. Main power must be supplied from a field or factory- supplied disconnect.

3.Wiring for main field supply must be rated 75 C. Use copper conductors only.

a. Incoming wire size range for terminal block with MCA (mini- mum circuit amps) up to 175 amps is 14 AWG (American Wire Gage) to 2/0.

b. Incoming wire size range for terminal block with MCA from

175.1 amps to 420 amps is 2 AWG to 600 kcmil.

c.Incoming wire size range for non-fused disconnect with MCA up to 100 amps is 14 AWG to 1/0.

d.Incoming wire size range for non-fused disconnect with MCA from 100.1 amp to 200 amps is 6 AWG to 350 kcmil.

e.Incoming wire size range for non-fused disconnect with MCA from 200.1 amp to 450 amps is 3/0 to 500 kcmil.

4.Terminals 1 and 2 of the LVT are for the alarm relay. The maxi- mum load allowed for the alarm relay is 5-va sealed and 10-va inrush at 24-v. Field power supply is not required.

5.Refer to certified dimensional drawings for exact locations of the main power and control power entrance locations.

6.Terminals 24, 25, and 2 of the LVT are for the control of the field-supplied LLSV. The maximum load allowed for the LLSV is 15-va sealed and 30-va inrush at 24-v. Field power supply is not required.

7.LLSV (24-v) should be 15-va maximum per valve as required.

8.Not used on single circuit unit.

9.Installation of fan status switch (FS1) is recommended.

10.The contacts for remote ON/OFF, fan status, and demand limit options must be rated for dry circuit application capable of han- dling a 24-vac load up to 50 mA.
